Title: Display of television images on large screens - is enhanced by modulating and multiplying display of horizontal lines
IPC: H04N7/01
Filed: 1973-06-18
Abstract: Where television images are displayed on large screens for an audience instead of on normal sized screens, shaded areas appear between the horizontal lines. To overcome this the horizontal lines are made to oscillate and also lines may be displayed two or more times. A video signal is applied to the input (11) of a circuit which enables a large screen to be employed. The input signal is passed via one channel (12) to two parallel switching circuits (15a, 15b) and then to two delay lines (17a, 17b). The input is also routed (13) to a phase comparator (57) where it is synchronised with the divided-down frequency of a voltage controlled oscillator (VCO) which controls the delay lines to give line multiplication.

Title: Ball indentation test - uses different radii of curvature to determine elastic limit changes in depth
IPC: G01N3/00
Filed: 1974-02-21
Abstract: Internal stresses and changes of the elastic limit of workpieces as functions of the depth under the surface can be determined without having to destroy any part of the workpiece. A ram with a hemispherical contact face of a specific radius of curvature is pressed against the workpiece surface with successively increased force until the plastic limit is reached. The surface deformation is measured and the principal stresses are calculated and recorded. The same test is repeated with different radii of curvature (60mm, 150mm, 200mm). The envelope of the curves of the principal stresses versus the penetration indicates the elastic limit as a function of the depth.
